METHOD FOR PRODUCING LIGHT AND STRONG CARBON COMPLEX MATERIAL OF ELECTRONIC SHIELDING

摘要

PURPOSE: A light strong carbon complex material is provided to have the excellent electronic shielding property by thermally processing and after-processing a reinforcing complex material of carbon fiber. CONSTITUTION: A light and strong carbon complex material is produced by hot pressing after making a prepreg of carbon fibrous complex fiber by drying after impregnating a single fiber or a fibrous mat formed by cutting a carbon fiber in a regular length in a high molecular resin. A material selected from a group formed by a filling agent, a hardening catalyst, a coloring agent, an inner release agent, and their compound into the resin after controlling the concentration of the resin using an acetone, an ethanol, or a methanol of 100-500% of the resin weight as a solvent to be the 45-90% content of the resin among the complex material of carbon fiber obtained finally.
